PURIFIER FOR GASES.

' Applicaiio" iled June 26- To all whom it may concern:

Be it known that I, WILLIAM T was, a subct of the King of Great Britain, residing at 001, in the county of Lancaster, Engiver land, ave invented new and useful Im rovements in Purifiers for Gases, of which the fol lowing is a specification, reference being had to the accompanying drawings, on which- F igurel is a longitudinal central section and Fig. 2 a transverse section of a purifier constructed according to myinvention. Figs. 3 and 4 are detail views at right angles to each other of one of the fans or dispersers.

The object of the invention is to provide simple and reliable apparatus whereby gases maybe more thoroughly washed and the tar or other impurities-removed to a greater extent than has been done hitherto. The apparatus is specially applicable to producer gas from bituminous coal but may be used for other I gases where suitable In carrying out my invention I construct apparatus substantially as shown on the drawings where 1 is a cylindrical casing or chamber, supported by brackets u on a foundation 2. The chamber is pre erably made in two parts so that the upper part can be removed for inspection.

3 are diaphragms in the chamber dividing it into several compartments.

4 are central or nearly central openings in 5 are end covers to the chamber.

6 is a central shaft supported in bearings 7 in the end covers and rotatable by a pulley 8 or otherwise as convenient.

9 are fans or dispersers fixed on the. shaft 6 one in each com artment. 'The fans consist each of a disk s ightly less than the internal diameter of the chamber and provided on o e side with blades or ribs 10 leading from middle part of disk towards the periphery as shown in Fig. 3.

, The fans are so disposed on the shaft that the blades 10 nearly touch the diaphragms 3 leaving clear s' aces 11 between the disks and the next diapliiragm. The diaphragms may be fitted loosely ber.

13 are pipes for the su ply of Water or fluid the en s 14 of the pi es are diverted into the openings 4 in the iaphragms so that the in grooves 12 in the cham- 15 are rforated'diaphragms dis osed in the chanr r on the exit side of the ast fan.

I 16 is the inlet for the I 1.7 is the outlet for the purified gas. l 18 are discharge pipes for the tar &c. from the cylinder depending into liquid in a well I 19 so that the pipes have a liquid seal. 20 overflow pipe from the well. l The action is as follows: The shaft 6 and fans 9 are caused to rotate at a high speed and the gas to be purified enters the chamber through the inlet 16 and passes through the I central opening 4 in the first diaphragm l where it is caught by the blades of the first fan or disperser and driven outwards by centrifugal action against the interior of the chamber walls where some of the tar or other I liquid or solid particles in suspension in the gas are separated and travel around down the chamber Walls to the discharge pipe18.

The gas after leaving the periphery of the first fan passes inwardly through the space 11 to the central opening 4 of the second diaphragm and comes second fan whereby it is again driven out against thechamber walls and a further again passing inwards to the central open' g o the third diaphragm and so on through the whole series, the gas finally passing through the perforations in the diaphragms 15 and thence through the outlet 17. In some cases tlgle dia hragms 15 might be dispensed with w ere t To assist in the purification I may inject .water or other suitable liquid through the pi cs 13 against the fans 9 the blades of wiich beat such liquid into fine spray and thoroughly mingle it with the gases passing outwardly along the fan blades the spray being driven' against the chamber walls, I carrying with it in solution some of the im purities which are easily soluble and thence passing to the discharge pipes 18. The iquid spray also serves to wash off the fan disk or blades any impurities which may collect thereon. The liquid supply may however be dispensed with if the impurities in l the gas are insoluble or nonadherent.

What I claim is 1. A purifier for gases consisting of a chamber divided into several compartments by diaphragms such diaphragms having approximately central openings, a rotating disperser in each compartment carried on a central shaft and formed of a solid diskwith free-ended and free edged blades onone side gas to the chambers into contact with the separation of impurities made, afterwards e purification by the fans is suflicient for the purpose.

only and arranged with the free edges of the blades close to the diaphragm on one side of a compartment and facing the entering gas,

and discharge pipes from the compartments, I

and the outlet, substantially asdescribed. ,3. A purifier for gases consisting of a chamber divided into several compartments 'by diaphragms such diaphragms having approximately central openings, a rotating disperser in each compartment carried on a central shaft and formed of a solid disk with free ended and free edged blades on one side only and arranged with the free edges of the blades close to the diaphragm on one side of of the dispersers, substantially as described a compartment and facing the entering and discharge pipes from the compartments and pipes for supplying liquid near the center 4. A purifier for gases consisting of chamber divided into several compartment by diaphragms such diaphragms havin approximately central openings, a'rotatin disperser in each compartment carried on centralshaft and formed of a solid disk with blades on one side and arranged close to the diaphra m on one side of a compartment'with the bla es facing the entering gas, and discharge pipes from the compartments, and at least one perforated diaphragm arranged in the chamber between the last disperser and the outlet, and pipes for supplying'liquid near, the centers of the dispersers, substantially as described. y

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
